Hello All: I am trying to create a select box that is filled with options based on the user''s selection in a related drop-down.

A newly released site developed entirely in Rails, known as Smatchy (www.smatchy.com), presents an interesting take on recommendations and could become the standard rather than the exception. The recommendations were more useful than typical sites, especially the ''Unique Recs.'' More info here...

Railsers: I switched from MySQL to Sqlite3 for Test-Driven Development. It meant the difference between (Long term, I want to understand the db:migrate system well enough that I can run a long test, occassionally, that migrates everything to MySQL and retests it there. That will prevent nasty surprises at deployment time. But that''s not the current question!) Because I don''t

Hi all, I followed the example on: http://www.roryhansen.ca/?p=9 for creating related drop-down lists. However, this code actually creates HTML in the controller component: @albums = Album.find_all_by_artist_id(@params["artist_id"]) @html = "<select id=''album_id'' name=''album_id''>" @html += "<option

I am attempting to use Ajax.Updater to update the innerHTML of a SELECT - that is, to feed it a list of <option>..</option> sets generated from a partial. It works as expected on FF1.5, but in IE6 it renders as an empty select. When I use the DOM viewer (or an alert()) to dump the value of innerHTML, it appears intact EXCEPT that the first <option> is missing with no

So I want to have a form with a drop down that lists all our customers. And when a user selects a customer, I want it to automatically list the customer names emails below the drop down. Anyone have any thoughts as the best approach to do this? I could just write javascript, but it seems like there would be a rails tag for this. thanks, phil -- Posted via http://www.ruby-forum.com/.

linked selects are critical to my application. for those who don''t know, a linked select updates as the select box it is linked to is updated. for example, if select 1 is "California", then select 2 will list all the cities in California. change select 1 to Washington and select 2 will automatically change to list all the cities in Washington. I use a php forms class to

This is probably more a Ruby question, but somebody here probably knows ;). Is there some handy Ruby or Rails library that can get data from other sites (like Amazon and Flickr) via REST, then return it in nice arrays, hashes, objects, etc.? I''ve searched quite a bit and haven''t been able to really find anything. There is a ruby-amazon library, but it''s for an older

Hi, I want to update a select box depending on another selected option thru ajax. Heres how I do it # _form.rhtml <select id="budget_coordinator_id" name="budget[coordinator_id]" onchange="<%= remote_function(:update => "budget_project_number", :url => { :action => :get_projects }) %>"> <%=

Hi all, I have a select helper form on a web page which contains a list of dates. When the user selects a date, one of the other forms on the page needs to be updated based on the newly selected date. Is there a way to catch this event in Rails? Are we talking Ajax here? Or is there a simpler way? Thanks, Dan

Hello All, I''m trying to capture the exception message that my server application is providing in response to my Ajax.Request. However, I''m confused as to when onFailure is fired vs. onException. The onException handler has access to the javascript exception object and I''d understood that it was only called when the dispatch fails. Not sure what exactly that means

I''m fairly new to Ruby & Rails and I come from a stricly M$ background. I''m trying to move into the world of open source, but I don''t have a good roadmap.

Hi. I''m going to start writting an ajax "tabs"" helper, but before starting to reinvent the wheel (and in order to avoid DRO : don''t Repeat Ourselves :-) ) I wish to know if there is any project for this already. Thanks.

Hi, It seems there must be a better way to do this than what I am currently doing. I have a simple app that collects a users thoughts along with their email address and their first an last name. On a page that lists all the users thoughts they can click on a link to "add a thought" which then displays a form with ajax. My current methodology for this is not very dry. If js is

I'm wrapping a function in R and I want to record all the arguments passed to it, including default values and missing values. I want to be able to snoop on function calls in sourced scripts as part of a unit testing framework. I can capture the values fine, but I'm having trouble evaluating them as if `force()` had been applied to each of them. Here is a minimal example: f0 <-

I am breaking ground on a new project and one of the issues I expect to encouter is the ability of users to define their own columns. For example, one of the features of this application will be the ability to store information about people''s skills and then search for and schedule them based on this information. Since every organization''s needs are different, it would be ideal
